Abstract
A casting is extracted from a horizontal mold by means of extraction cycles with a shallow speed rise followed by a steep one, followed by a constant speed phase, followed by a rapid slowdown, and brief reversal. The casting is held by brackets which operate from above and below with separate bracket drives but parallel axes of action.
